This work is concerned with the oscillatory behavior of solutions of fourth-order neutral
differential equations. By using the Riccati transformation and integral averaging techniques …

The objective in this work is to study oscillation criteria for second-order quasi-linear
differential equations with an advanced argument. We establish new oscillation criteria …

The Wheeler–DeWitt equation for a flat and compact Friedmann–Lemaître–Robertson–
Walker cosmology at the pre-inflation epoch is studied in the contexts of the standard and …

Nonlinear science is very common and important natural phenomenon in our surroundings.
It is quite possible to find a large number of phenomena, which become a cause of the …

In this study, we join the concept of fractality introduced by Li and Ostoja-Starzewski with the
concept of nonlocality to produce a new set of nonlocal fractal fluid equations of motion. Both …

We study the oscillatory behavior of a class of fourth-order differential equations and
establish sufficient conditions for oscillation of a fourth-order differential equation with middle …

The motivation for this paper is to create new criteria for oscillation of solutions of second-
order nonlinear neutral differential equations. In more than one respect, our results improve …

The paper is devoted to the study of oscillation of even-order neutral differential equations.
New Kamenev-type oscillation criteria are established, and they essentially improve and …

In this paper, new sufficient conditions for oscillation of fourth-order neutral differential
equations are established. One objective of our paper is to further improve and complement …
